Confused by Contradictory Polls? Take a Step Back

nytimes.com – It has been a rocky few weeks all over the world. Only a few surprising presidential poll results have broken through in a news cycle dominated by shootings by and of the police, the F.B.I.’s decision not to indict Hillary Clinton, Donald Trump’s vice-presidential pick, more terror in France and an attempted coup in Turkey.

In truth, around 50 state and national polls were released this past week. Individually, they have sometimes felt as chaotic as the news around the world. But together they tell a far clearer story: Mrs. Clinton holds a modest but clear lead heading into the conventions.
